1 End Show Slide 1 of 21 Copyright Pearson Prentice Hall Biology

2 End Show Slide 2 of 21 Copyright Pearson Prentice Hall 1-1 What Is Science?

3 End Show 1-1 What Is Science? Slide 3 of 21 Copyright Pearson Prentice Hall What Science Is and Is Not What is the goal of science?

4 End Show 1-1 What Is Science? Slide 4 of 21 Copyright Pearson Prentice Hall What Science Is and Is Not The goal of science is to: investigate and understand the natural world. explain events in the natural world. use those explanations to make useful predictions.

5 End Show 1-1 What Is Science? Slide 5 of 21 Copyright Pearson Prentice Hall What Science Is and Is Not Science is an organized way of using evidence to learn about the natural world. Think about CSI

6 End Show 1-1 What Is Science? Slide 6 of 21 Copyright Pearson Prentice Hall

7 End Show 1-1 What Is Science? Slide 7 of 21 Thinking Like a Scientist How do scientist including YOU think!!! Problem/Question Observation/Research Formulate a Hypothesis Experiment Collect and Analyze Results Conclusion Communicate the Results http://glencoe.com/sec/ science/physics/ppp_0 9/animation/Chapter% 201/Scientific%20Meth od.swfhttp://glencoe.com/sec/ science/physics/ppp_0 9/animation/Chapter% 201/Scientific%20Meth od.swf Copyright Pearson Prentice Hall

8 End Show 1-1 What Is Science? Slide 8 of 21 Steps of the Scientific Method Problem/Question 1. Problem/Question: Develop a question or problem that can be solved through experimentation.

9 End Show 1-1 What Is Science? Slide 9 of 21 Steps of the Scientific Method Observation/Research 2. Observation/Research: Make observations and research your topic of interest.

10 End Show 1-1 What Is Science? Slide 10 of 21 Do you remember the next step?

11 End Show 1-1 What Is Science? Slide 11 of 21 Steps of the Scientific Method Formulate a Hypothesis 3. Formulate a Hypothesis: Predict a possible answer to the problem or question. Example: If soil temperatures rise, then plant growth will increase.

12 End Show 1-1 What Is Science? Slide 12 of 21 Steps of the Scientific Method Experiment 4. Experiment: Develop and follow a procedure. Include a detailed materials list. The outcome must be measurable (quantifiable).

13 End Show 1-1 What Is Science? Slide 13 of 21 Formulate a Hypothesis After talking with his teacher and conducting further research, he comes up with a hypothesis. “If more sugar is added, then the bread will rise higher.”

14 End Show 1-1 What Is Science? Slide 14 of 21 Hypothesis The hypothesis is an educated guess based on some type of evidence. Hypotheses are tested by performing controlled experiments or by gathering new data.

15 End Show 1-1 What Is Science? Slide 15 of 21 Do you know the difference between the independent and dependent variables?

16 End Show 1-1 What Is Science? Slide 16 of 21 Independent Variable The independent, or manipulated variable, is a factor that’s intentionally varied by the experimenter. John is going to use 25g., 50g., 100g., 250g., 500g. of sugar in his experiment.

17 End Show 1-1 What Is Science? Slide 17 of 21 Dependent Variable The dependent, or responding variable, is the factor that may change as a result of changes made in the independent variable. In this case, it would be the size of the loaf of bread.

18 End Show 1-1 What Is Science? Slide 18 of 21 Control Group The control is the group that serves as the standard of comparison.

19 End Show 1-1 What Is Science? Slide 19 of 21 Steps of the Scientific Method Collect and Analyze Results 5. Collect and Analyze Results: Modify the procedure if needed. Confirm the results by retesting. Include tables, graphs, and photographs.

20 End Show 1-1 What Is Science? Slide 20 of 21 Steps of the Scientific Method Conclusion 6. Conclusion: Include a statement that accepts or rejects the hypothesis. Make recommendations for further study and possible improvements to the procedure.

21 End Show 1-1 What Is Science? Slide 21 of 21 Steps of the Scientific Method Communicate the Results 7. Communicate the Results: Be prepared to present the project to an audience. Expect questions from the audience.

22 End Show 1-1 What Is Science? Slide 22 of 21 Copyright Pearson Prentice Hall Thinking Like a Scientist Scientific thinking begins with observation. Observation is the process of gathering information about events or processes in a careful, orderly way using your five senses. List your five senses.

23 End Show 1-1 What Is Science? Slide 23 of 21 Observation List 5 observations about this class. 1. 2. 3. 4. 5.

24 End Show 1-1 What Is Science? Slide 24 of 21 Copyright Pearson Prentice Hall Thinking Like a Scientist The information gathered from observations is called data. Quantitative data -uses numbers Qualitative data -uses words

25 End Show 1-1 What Is Science? Slide 25 of 21 Check For Understanding 1.Describe the goal of science in your own words. 2.Can the Scientific method start in any order? Copyright Pearson Prentice Hall

26 End Show 1-1 What Is Science? Slide 26 of 21 Copyright Pearson Prentice Hall Thinking Like a Scientist Scientists use data to make inferences. An inference is a logical interpretation based on prior knowledge or experience. Do NOT WRITE THIS For example, if you get up in the morning, look up at the sky and observe dark clouds, observe the air is cool and humid, and observe puddles on the ground. What can you infer?

27 End Show 1-1 What Is Science? Slide 27 of 21 Copyright Pearson Prentice Hall Observations involving numbers are known as A. qualitative observations. B. hypothetical observations. C. quantitative observations. D. inferred observations.

28 End Show 1-1 What Is Science? Slide 28 of 21 Copyright Pearson Prentice Hall Observations involving numbers are known as A. qualitative observations. B. hypothetical observations. C. quantitative observations. D. inferred observations.

29 End Show 1-1 What Is Science? Slide 29 of 21 Copyright Pearson Prentice Hall 1–1 Which is NOT a type of data that uses words? A.Quantitative B.Qualitative

30 End Show 1-1 What Is Science? Slide 30 of 21 Copyright Pearson Prentice Hall 1–1 Which is NOT a type of data that uses words? A.Quantitative B.Qualitative

31 End Show 1-1 What Is Science? Slide 31 of 21 Copyright Pearson Prentice Hall Science and Human Values Decisions involve many factors besides scientific information, including: the society in which we live economic considerations laws moral principles Citizens decide what to do when they vote.

32 End Show Slide 32 of 21 Copyright Pearson Prentice Hall 1–1 A scientist takes paint chips from 10 apartments in a large building. She tests for the presence of lead in the paint and finds it in all 10 samples. She then concludes that lead paint is probably present in all 120 apartments in the building. This conclusion is an example of a.a scientific fact. b.a scientific error. c.proof. d.a reasonable inference.

She tests for the presence of lead in the paint and finds it in all 10 samples. She then concludes that lead paint is probably present in all 120 apartments in the building.

34 End Show Slide 34 of 21 Copyright Pearson Prentice Hall 1–1 A possible explanation for a set of observations is known as a.data. b.a hypothesis. c.an inference. d.a result.

35 End Show Slide 35 of 21 Copyright Pearson Prentice Hall 1–1 A possible explanation for a set of observations is known as a.data. b.a hypothesis. c.an inference. d.a result.

36 End Show Slide 36 of 21 Copyright Pearson Prentice Hall 1–1 A good scientific hypothesis must be a.correct. b.able to be tested. c.obvious. d.based on common sense.

37 End Show Slide 37 of 21 Copyright Pearson Prentice Hall 1–1 A good scientific hypothesis must be a.correct. b.able to be tested. c.obvious. d.based on common sense.
